Free QuoteThere are numerous standards defining the interconnection and disconnection of single-phase inverters to utility grid available. The solar inverters are one of the most extensively researched topics in emerging power electronics due to their variety in circuit and control architectures.
In grid-connected PV system, inverter with the current control mode is extensively used because a high power factor can be obtained by a simple control circuit, and also suppression of transient current is possible when any grid disturbances occur. Table 3.
Today improvement of existing Grid-Connected PV inverters are mainly linked to a reduction of overall Grid-connected PV system costs. The efficiency of a Grid-Connected PV inverter is above 98% and not longer the primary focus of development, though a high efficiency is a prerequisite for any kind of successful system.
Thus, this work presents the modeling and control of a single-phase grid-connected multifunctional converter, which operates as a current-controlled voltage source inverter using an LCL-type output filter.
Summary of grid-connected PV inverter topology In the grid-connected PV system, the DC power of the PV array should be converted into the AC power with proper voltage magnitude, frequency and phase to be connected to the utility grid. Under this condition, a DC-to-AC converter which is better known as inverter is required.
This paper presents the control strategy of a single-phase LCL-Filter grid connected inverter for PV applications. It compares three grid interfacing passive filters topologies to validate their performance and effectiveness.
